The real-time Dst index is only for monitoring, diagnostics, and forecasting purposes.
Since the values are derived from unverified raw data, they may contain inaccuracies.
The observatories as well as we have no responsibility for inaccuate values caused by noises and baseline shifts.
Hourly values given here will be replaced by provisional and final values at later dates.
